So I tried posting this in the Parts wanted section but didn't have any replies, so I thought I would try a post here. Both of my front door interior door handle / arm rests for my 1981 300sd w126 broke in the same place which is the middle connector for the arm rest - between the handle and the door. This is a small squarish piece that has two screws connecting it to the door handle and a larger screw connecting it to the door.

Both of the arm rests middle connectors broke in the same place which is the plastic area that the screw that connects it to the door goes through.

The piece looks like it is designed to be replaced in situations like this, however I have not been able to find this replacement part? The rest of the door handle on both doors is just fine, just this middle portion / connector.

Does anyone have any leads on where I can get a replacement or how I can try to fix this aside from purchasing an entire used door arm rest / handle?

Thank you in advance.
